To all whom it may concern Be it known that I, AUGUSTE DACCOBD, a

citizen of the Republic of Switzerland, and

a resident of the city of New York, in the county and State of New York, have mvented a certain new and useful Improve-' ment in Bottle-Closures, of which the folis a specification, reference being had therein to the accompanying drawing.

and cream.

This invention relates to stoppers for bottles, and more particularly. to devices of the kind which are used in connection with wide-mouthed bottles designed to hold milk Numerous contrivances have heretofore been devised for the purpose of providing a suitable closure for the orifice of a milkbottle, but in so far as I am aware none that has proved to be entirely satisfactory, considered both with reference to ease of manipulation and from an economic standpoint. Perhaps the least expensive and most employed form of stoplper of this type formerly in use was that w 1ch consisted of aflat disk of paper, and was rammed tightly into the mouth of the milk-bottle, wherein it rested at the edge uponan internal flange formed in, the bottle-neck. A stopper of that sort answered'the purpose to the extent that it closed the bottle until first opened after delivery, butit was subject to the positive disadvantage of requiring the use of a tool or some sharp instrument for its removal. This most always resulted in punc- 'turing or cutting up the paper disk, and consequently the same could not thereafter be replaced in the mouth of the bottle, if so desired, and serve again as a dust-proof clo-' sure.

The principal object of the present invention is to provide an im roved closureof the Figure 1 is a sectional elevation, showing I the neck or upper part ofa milk-bottle, with 7 this improved closure thereto applied;

Fig. 2 is a similar view, illustrating the manner of removing the closure from the mouth of the milk-bottle; a Fi 3 is a perspective view of the closure, detac ed, lookin at the top thereof; and

Fig. 4 is anot er perspective view of the closure, looking 'at the under side of the same.

vention is readily? applied to a milk-bottle,

indicated by the numeral 11 such as is em- .products. This form "of bottle, it will be As. represented in Figs. 1' and 2, the in-,

.noted,has'a wide neck 12, with aproportion'ately large mouth 13, and an internal ledge 14, constitutin an annular abutment at the division line etween the mouth and neck. Ordinarily, the bottle is filled'up to within a' small fraction of anlinch of the led e or abutment.

akin the bottle above described, the improve closure adapted therefor consists of a slightly conical disk 17, of .convexoconcave formation, adapted to be seated at its perimeter upon the ledgeor abutment 14 aforesaid. This disk is conveniently made of smooth cardboard, calendered, and stamped in one piece with suitable dies, of the form and dimensions required to suit the various requirements. Itis given sufficient flexibility to permit inversion, that is, to be readily changed, by pressure there: on, from the convexo-concave to the concavo-convex shape, and the reverse, at option. Atthe same time, enough rigidity is imparted to the disk to render it capable of retaining the desired form in normal conditions. It is further made somewhat larger than the internal, area of the mouth of the bottle, that it may press lightly all around the same at the outer circumference of the ledge or abutment.

It will be observed that when set in within the mouth of the bottle, as illustrated in Fig. -1, the disk 17 stands therein with its apex a little below the top of the bottle,

so that if the latter were turned upside.

of the liquid, as milk or cream, in the bottle, which provides -all the requisite clearance for the inversion of the cone of which the closure is formed.

Now, it will be perceived that, in order to remove the closure, the only thing needed is to press down, for instance with the the inversion of the cone, and then -a sh ht with the thumb will eject the disk, 1 er 'the manner suggested in Fig. 2. In case the bottle is not emptied at once of all its contents, it is a simple matter to restore the disk to its original shape, or else to reverse it, and put it back in the mouth of the bottle, which can thus be opened and closed repeatedly, without the use of any tool.

\ Although theinvention has been shown and described as a closure especially adapted for use on a milk-bottle, it should be understood that no undue limitation of the invention is intendedin that res ect. Obviously,

this improved closure coul be used on 'ars and various types of containers other t an bottles for holdin milk or cream. The contents of the jars, ottles, or similar vessels, of course, have little if any bearing on the invention, in so far as the construction and operation of the closure are concerned.

Having described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

The combination with a bottle or similar 40 i vessel having a relatively wide neck, a proportionately large mouth, and an internal abutment therebetween, of a slightly con'i cal convexo-concave disk adapted to be seated at its outer edge upon said abutment and form a tight closure thereon with its apex below the topv of the bottle or vessel,

said disk admitting of inversion by' pressure upon its said apex, being'thereby disengaged from its seat on'the abutment and positloned for ejection from the bottle or' vessel by a thrust in a substantially lateral direction.

In testimony whereof I havesigned my name to this specification.
